Bulb Size by Year Range

Years	Bulb Size
2004-2005	192

Description	Bulb Size
ANSI standard (US & Canada). Miniature wedge bulb (T10). 12V, 3W.	192

The T10 miniature wedge is the bulb type used in the GMC Envoy XUV license plate position. This form factor features a wedge-shaped base that connects directly into a socket without a separate metal base or pins, relying on the glass envelope itself to make contact.
The 192 bulb operates at 12 volts and draws 3 watts, placing it among the lower-wattage bulbs in automotive lighting applications. This output level is typical for illumination purposes rather than signaling functions.
The 192 designation follows ANSI standardization recognized in both the United States and Canada, meaning the specification reflects a consistent electrical and physical standard across North American markets.
The GMC Envoy XUV carries the 192 bulb size for the license plate across the 2004-2005 model years. Both years share an identical specification with no variation between them.
Because the T10 wedge base is a widely produced form factor, the 192 bulb is interchangeable with other T10-based bulbs that match the 12V and 3W ratings. Substitutions using different wattage ratings within the same socket type may not conform to the original specification.
